A typical OV staircase system is located within a protected stairwell and consists of either an actuated window or a roof-mounted ventilator unit (providing a free area of 1.0m2) and a zone control unit (networked if it connects to other zone control units).
Fire officer over-ride switches are provided at the fire service entrance level. Smoke detectors can be added if the stairwell and building layout require them.
